Open Close Door is an indie project I’m creating alone in my free time — purely out of love for classic retro FPS games.
Don’t expect a massive AAA production, but if you appreciate the authentic atmosphere of 90s shooters and handcrafted content, I believe this game will grab you.
Every wishlist and bit of support means a lot to me. 🙏

Toto je popiči projekt, pripomína mi časy z Doomu.ano sú tam chybičky, ktoré sa za ten čas opravili a stále sa na nich pracuje. možno mi trošku vadí to svetlo v štvrtom leveli. občas som nevedel, že kde ísť, ale vždy som našiel cestu. som rád, že som mohol dať ruku k umeniu. a čo je ešte lepšie, že sa našli ľudia čo dabujú postavy. Teším sa na dvojku O.C.D.
My name is Walkht Agent Walkht It's been over a year since I lost everything I live off jobs froom people work has cost me everything LOVE, FUTURE, FAMILY, HOME. But habits habits are like an iron shirt. - open close door, every time you die, for 2 minutes straight
Top game, try it ..
Naprosto super hra v old school stylu. Je to hraní tak na chuť, ale nic úplně jednoduchýho. Párkrát jsem zhebnul hned v první úrovni, ale možná proto mě to baví. Je to prostě old school shooting zábava za pár kaček, kterými rád podpořím Cranea.
BAD!!! LIKE REALLY BAD!!! The game is too dark with no way of turning up the brightness or having a flashlight in the game or just any way to see. It's just constantly dark I actually had to turn up the contrast on my monitor. The typos in spelling errors from the AI slop is pretty funny though. I saw that in the screenshots of the game but I thought the Boomer shooter aspect of it might be fun but it really wasn't. Every level is the same thing collect key cards the search for the exit. Doom does the same thing but at least we do there's a map that you don't get super freaking lost and have no clue where to go most of the time. And Doom is fun where this game is so boring. Again the only positive thing I can say about this is the AI slop story is so comically terrible and made me laugh a few times. But just don't buy this game and absolutely stinks.
